TAnimateImage is a windowed control similar to TImage for displaying images of an image list on a form. You only need to assign a TImageList component (or its descendant) to its Images property, and set the FrameIndex property to the index of your desired image on the image list.

Of course, TAnimateImage can animate images of an image list too. If you have frames of an animation as Bitmap or Icon, this component offers the easiest way to animate them. For this purpose, TAnimateImage provides some properties to specify interval, segment, and direction of images for the animation.

TResourceAllocationChart draws a chart suitable for showing the allocation of shared resources. Those resources could represent shared rooms, cars, in fact anything at all.

Once you have a chart, you can:

• add or delete resources.
• add or delete allocations for each resource.
• change the bar style and colour of any resource, or of any allocation of a resource.
• change the appearance of any particular allocation by changing the pen or brush attributes in the OnAllocationDraw event, or by using the OwnerDraw style.
• drag the chart right or left.

• drag an allocation from one resource to another. This can be useful if, for example, the resource becomes unavailable.
• click and drag the end of an allocation to expand or contract it.
